Out at a remote jobsite last spring, the GIS/Surveyor techs asked if I wanted the Sprinter scanned. This is with LiDAR, Light Detection and Ranging (kind of like Radar but with laser beams) that gives very precise measurements (usually to real-world coordinates, so this Sprinter could be placed on Google Earth precisely where the scanning was done. Each dot has x,y and z coordinates in UTM!). The quarter-million $ machine measures points to a mm accuracy a few mm to a few cm apart, giving amazingly detailed measurements and images of the ground, a building, a Sprinter etc.
You can see the individual measurement points as rows of dots, as the laser scanned back and forth. THe solid 'white' parts like on the door or the Mercedes badge area are where they got the instrument to do very tight measuring, so the dots are overlapping (until you zoom in). On the colourized versions where there is a colour change, the instrument has detected a different material type as part of its remote sensing capability.
The bottome is fuzzy or missing in places because there was grass in the way and the instrument couldn't 'see' the van.
Anyway, kind of fun, I didn't get a screen cap of the inside looking out, etc. I'll try and do that soon.
